..one of my most favorite photo memories...i came upon these guys in Jasper (Alberta Canada above Banff) and chased them over hills for more than an hour...they always stayed just out of camera range...finally the older fella decided to pull up and graze...he was aware of my presence but finally comfortable with me...perhaps it was the peanut butter sandwitch that i tossed his way (don't tell the park rangers)...it was a gas to watch them frollick..and man, can they handle some tough terrain--they wore me out..
